SPECIFICATION forming part of Letters Patent No. 783,555, dated-February 28, 1905.

Application iiled August 7, 1903. Serial No. 168,603.

le it known that I, CLINTON D. Tnnon, a citizen of the United States, residing at New York, in the county and State of New York, have in vented. new and useful Improvements in vWindows, of which the following is a specilication.

lhis invention relates to that class of windows in which the sash is mounted to turn horizontalhT in the frame for opening' and closing the same and to move vertically for locking or unlocking the same.

One of the objects of this invention is to provide simple and reliable means whereby the sash may be easily raised and lowerediand held in either position.

Another object of this invention is to provide means for relieving the top of the sash from the friction of the weather-strip upon opening' or closing the same.

A further object of this invention is to improve the means for retaining the ends of the weather-stri p in place.

VFig. 2l is a frag mentary top plan view of the sash and the 'lacewplate thereon. Fig. isa fragmentary vertical transverse section, on an enlarged scale, in line 22 22, Fig. l, showing the means for holding the. end o l' the weatherestri p in place.

Similar letters of reference indicate eorrespending parts throughout the several views.

A represen ts the wimlow-frame; l, the sash arranged in the frame; C, the bed or strip arranged beiow the sash and secured to the sill l), and E the weather-strip arranged betweel'l the top of the sash and the frame.

lhe sash is so mounted on the frame that it can be raised and lowered a limited extent lor unlocking or iocking the sash and that it can also be turned in a horizontal plane for open` ing or closing the same. On the under side oli its lower rail the sash is provided with a longitudinal groove and the opposing upper side of the bed is provided with a longitudinal rib or tcnon c. 1n the normal closed and lowered position of the sash its groove /i is engaged by the tenon, thereby preventing the sash from turning horizontally and also forniing a weather-`tight joint between the sash and frame at this point, as shown in Fig. E2.

F F' represent the metal face-platos of the fixture whereby the lower end et Vthe sash is pivoted vertically to the frame. The faceplate F is secured leilgthwise to the central part of the bed-strip and is provided centrally with a vertical cylindrical socket f and on the opposite sides ol the socket with tenons` or ribsf, which form contimnitions of the wooden rib e of the bed, as shown Vin Fig. 16. The bottom fi of the socket contains an oblong opening f.

Gr represents a bearing or coupling block provided on its under side with a depending cylilidrical pivot or trunuion y, which turns in the socketf. This trunnion i'iormally held against upward movement in the socket by an enlarged or "lshaped coupling-hostil g',

projecting from its under side through the oblong opening in the bottom of the socket and normally engaging its extremities with the under side of said bottom. For attaching the bearing-block to the bed face-plate the block is turned so that its coupling-head registers with the opening f3 in said plate and then passing' said head through said opening' and turning' the same so that its extremities are carried underneath the socket-bottom on opposite sides of the narrow part of the opening therein.

The face-plate Fl is attached to the under side of the lower sash-rail. This plate is provided centrally with an opening t, in which the bearing-block is guided, and on opposite sides of said opening with longitudinal grooves 7L', which receive the ribs f' of the bed face-plate and form continuations of the groove Z) in the wooden part of the bed. The sides of the opening /t-in the lower sash face-plate are flat or angular, as shown at z' in Fig. let, and the part t" of the bearing-block above its trunnion which enters the opening /L is of correspondingly angular form, thereby coupling' the lower sash-plate and the trunnion, so as to compel these parts to turn together horizontally, but permitting the sash to slide vertically on the trunnion. Above the lower face F the sash is provided with a recess 2 in line with the opening /L in the plate.

.l represents a bracket arranged on top of the lower sash-plate within the outer part of the recess and provided on opposite sides with vertical guideways or [langes j, between which the upper part of the bearing-block is guided. For convenience in manufacturing, the bracket is preferably iliade separate from the sash face-plate and connected therewith by bolts y" passing through the plate and lugs f3 on the bracket.

K represents an oscillating wedge for moving the sash vertically. This wedge is curved or crescent-shaped and arranged on the inner end of a cylindrical body r, which is journaled in a horizontal bearing 711 in the bearing-block above the trunnion, as shown in Figs. 8, 9, and ll. At its outer end the wedge-body has a spindle m, which projects through an opening m' in a wall at the outer wall of the bearing le.

a represents a shifting lug projecting'from the inner side of the bracket J into the path of the concave side ofthe wedge. Upon turning the wedge forwardly in the direction of the arrow, Fig. 9, the same advances with its narrow end and moves its gradually-widening part between the lower part of the cylindrical bearing and the under side of the shifting lug fa, whereby the latter is raised, as shown in Fig. 8, together with the sash and the parts mounted thereon. Upon turning the wedge in the opposite direction the same advances l narrowing parts between the shifting lug and the opposing lower side of the bearing, thereby permitting the lug and sash to descend by gravity.v Vhile raising and lowering the sash the wedge cannot move vertically with the same, because its bearing holds it against such movement. 1f for any reason the sash should bind and not descend freely during the return movement of the wedge, the same upon moving between the upper sides of the lug and the bearing will force the sash down. At either extremity of its movement the concave side of the wedge bears against the upper and lower ends of the shifting lug, whereby the sash is firmly held either in its open or closed position. In the lowered position of the sash the narrow end of the wedge engages the under side of the shifting lug and while the wide end of the wedge bears against the top of the lug, as shown in Fig. 9; butupon turning the wedge half-way round the narrow end of the wedge engages with the top of the shifting lug and its wide end against the bottom thereof, as shown in Fig. 8. The turning movement of the wedge is preferably effected by means of a lever or handle P, secured to the outer end of the spindle mf. This lever is so applied that it projects horizontally from one side of the spindle in the closed position of the sash and horizontally from the opposite side of the spindle in the open position of the sash. As the lit between the lug n and the wedge is liable to be rather loose, the place at which the wedge stops upon closing the sash would be indclinite, and therefore cause the handle P to assume a more er less inclined position at this time, and therefore be unsightly. ln order to avoid this, a separate stop device independent of the wedge and lug is employed for definitely arresting the cam when the sash is closed. This stop device preferably consists of a stop-lug o, arranged in the bearing ./1, and stop-lugs o o2, arranged on diametrically opposite sides of the spindle fm., and adapted to engage alternately with opposite sides of the stationary stop-lug o.

Q, represents a front plate secured to the inner side of the sash so as to cover the recess il. This plate is provided witha vertical slot q, through which the wedge-spindle projects and which is of sufHcient height to permit the sash to be raised and lowered freely by the wedge. At its lower edge the cover-plate is provided with inwardly-projecting lugs q', which lit into corresponding recesses q2 in the adjacent edge of thelower sash face-plate, as shown in Figs. l0, i7, and 18, thereby insuring proper alinement of these parts in applying them to the sash.

The throw of the wedge is such that the sash may be raised somewhat more than the height of the rib on the bed-strip, so as to with the wide end and presents its graduallyl permit the sash when elevated to be turned TIO IIS

reacts horizontally clear ol the rib into a more or less open position, as shown by dotted lines in Fig. 3.

ihe construction ot' the shitting wedge herein shown permits the sash. to be aised and lowered easily, gradually, and uniformly throughout the entire movementotI the wedge. .ln all positions of the wedge a part of the same is interposed directly between the under side ol the lug` a and the lower side of the bearing in which the wedge is journaled, thereby providing a solid and [irrn support At'or the sash which is not liable to give way. The wedge is also unatt'ected by the weight ol the sash, thereby preventing' the sash trom descending suddenly and jerking the operatingcrank while in the hand ol, the attendant. ldurthermore, the wedge forms a positive locl; which holds the sash securely in its elevated or depressed position, thereby avoiding the necessity lor employing a separate lock for this purpose, l

.ln the closed position otI the sash the coupling-head y ol the lower pivot-fixture is arranged crosswise underneath the bottom f2 ol the socket, thereby preventing` the lower pivot from being li'ltcd out ot' its socket while the parts are in this position if an attempt is made to open the sash 'from the outer side while the same locked down by the wedge.

'.lihc upper part otl the weather-strip is arranged in a longitudinal channel lt, formed on the under side of the adjacent frame-head, and the under side et the strip is provided with a longitudinal' tenou, bead, or rib s, which normally engages with a corresponding groove s in the upper edge ot' the top sash-rail. 'lrhe opposingl central parts ot' the weatherstrip and the top sash-rail are provided with metal lace-platesl` U, which are provided with a cooperating tenon and a groove forming a continuation of the tenon and groove in the adjacent wooden parts of the strip and rail, as shown in Figs. f2() and 2l.

r represents a vertical pin whereby the up-i per end of the sash is pivoted on the head of the t'rame. This pin is provided at its upper end with a base-plate fr', which is secured to the bottom o'l'f the channel R, while its lower end projects downwardly through openings t i" t, :formed centrally in the weather-strip E, strip-plate l, and upper sash-plate U and into a recess t, tormedin the upper sash-rail below the 'tace-plate U.

V represents a spring surrounding the pivotpin and bearing at its opposite ends against the base or' the pin and the upper side oi the strip tace-plate. The opening I; in the strip is made suiiiciently large to accommodate the spring' and to expose the strip-plate to -provide a shoulder or bearing for receiving the lower end of the spring.

rlhe recess t" in the upper sash-rail must be et' sui'licicnt depth to provide the requisite play between the bottom ol the recess and the lower end of the pivot-pin for permitting the sash to be raised clear oi the rib on the bedstrip. In order to secure the required depth of the recess for this purpose, the under `side of the upper sash-plate is provided on opposite sides ol' its opening t with depending gage-lugs ym, which are ol" a height equal to the required depth ot' the recess t. The carpenter in litting the upper sash-plate to the upper sash-rail is thus compelled to recess the latter sulliciently to receive the gage-lugs, thereby incidentally forming the recess ot' the proper depth to provide the required play between its bottom and the lower end ol the pivot-pin. lo permit ol convciiicntly installing the sash, the recess il in its top extends to the inner side thereof, thereby enabling the upper end ot' the sash to be engaged with the pivot-pin by moving the recessed part of the sash laterally relatively to the pivot-pin altcr the lower end of the sash hasbeeu pivotally connected with the bed-strip. The side of the recess I is normally closed by a depending cover-plate fm', which is formed integrally with the upper sash-plate and the gage-lugs fw and is secured to the inner side olf the sash by screws or otherwise.

For the purpose et' permitting the sash to be turned open easily alter the same has been raised and unlocked, a shifting device is provided which autouiatically tilts the weatherstrip and disengages its rib from the groove of the sash during the operation olE raising the same. This shitting device comprises a [inger or tail :c projecting' outwardly 'from the weather-strip and a stop af arranged on the frame-head in position to be engaged by said tail. The latter is preferably formed in one piece with the stri p-plate, and the sto p pre ferably consists oi a screw which permits ot' adjusting' the position of the stop relatively to the tail. lV hen the sash is in its lowered and closed position and the weather-strip engages :fully on its under side with the upper edge et' thel sash, the tail :n is arranged some distance belowl the stop m, as shown in Figs. Lt" and During the lirst part of the upward movement of the sash for unlocking the same the weather-strip rises with the sash without shitting the strip relatively to the sash; but during the last part of the rising' movement of the sash the tail :n et the weather-strip engages the stop a" and arrested by the latter, thereby causing the weather-strip to be rocked transversely along its outer lower edge on the sash and lifting its rib out of the groove ot the sash, as shown in Figs. 6 and 7. ltlhile the parts are in this position, the sash can be turned 'freely and easily into an open orclosed position with little el'liort. ln the absence ot' the strip-tilting device the disengagement of the sash and weather-strip would be eticcted solely by the wedge action ot' the interlocking groove and tenen, which would require more power owiifig to the unfavorableleverage and IOO IIO

the spring-pressure which resists the disen-y gagement of the tenon of the weather-sti'ip from the g'i'oove of the sash. Upon closing the sash and lowei'ing the same into its locked position the tail reeedes from the stop af, thereby permitting' the weather-strip to resume its normal position for producing a tight joint between the upper pai't of the sash and frame.

At opposite ends of the weather-sti'ip retaining' devices are provided which hold the strip firmly against the sash when closed and also prevent the strip from sag'ging when the sash is tui'ned open. Each of these retaining devices is consti'ucted as follows: Y represents a cylindrical thimble, which is provided about midway with an internal downwardly-facing shoulder 1/ and an external flange Near each end of the weather-strip the same is provided with a vei'tical socket comprising' a reduced lower portion 1/2 and an enlarged upper portion y, forming an upwardly -facing shouldei' y" between the two parts of the socket. The lower end of the thimble is fitted into the lower part y2 of the socket and its extei'nal flange is engaged with the internal shoulder of the socket. represents a stop having the form of a screw which extends through the thimble and bears with its head at its lower end against the internal shoulder thereof, -while its upper threaded end is secured in the bottom of the channel. e represents a spring surrounding the upper end of the thimble and bearing atits opposite ends against the flange of the thimble and the bottom of the channel. In the normal position of the parts (shown in Fig. 22) the springs e exert sufficient pressure against the weathersti'ip to hold the ends thereof firmly against the sash. Vhen the sash is tui'ned open, the ends of the sti'ip are sustained by the stopsci'ew limiting' the drop of the weather-strip at its ends and pi'eventing the same fi'om interfering with the sash upon subsequently turning the sash into a closed position. As shown in the drawings, the thiinbles are secured in the weather-strip by a drivinglit; but, if desired, the same may be secured by a screwfastening or other means.

On its outer side immediately above its lower edge the sash is provided with a horizontal defiecting strip L', havingl a longitudinal concave groove 722 in its underside. 7ater running down the outer side of the sash is deflected outwardly and caused to di'op on the sill beyond the bed-strip, while the groove in its undei' side prevents the water from creeping inwardly on this side of the strip b to the sash, thereby preventing this water from reaching the joint between the sash and bedstrip and passing' through the same. Below vthe joint between the lower end of the sash and the bed-strip the latter is provided on its outer side with a horizontal groove c, which is concave vertically. Any rain which is driven during a storm sidewise into this groove of the bed-sti'ip is deflected away from the joint between the bed-strip and sash,`and thus reduces the liability of water passing' through the window at this joint.
